THE UPSIDE POTENTIAL OF EQUITIES
WITH THE SECURITY OF U.S. TREASURIES
- -----------------------------------------------------------------------------

The investment objective of this Trust is to preserve capital while
providing for capital appreciation through an investment in "zero-coupon"
United States Treasury obligations (the "Treasury Obligations") and equity
stocks (the "Stocks") having, in the Sponsor's opinion on the Initial Date of
Deposit, potential for appreciation. The value of the Units will fluctuate
with the value of the portfolio of underlying securities.

The minimum purchase is $250. Only whole Units may be purchased.

* On the date of this Prospectus (the "Initial Date of Deposit") the
Public Offering Price is based on the value of the Securities as of
the close of business on January 28, 1998 (the business day preceding
the Initial Date of Deposit). However, if the public offering price
determined with reference to values of the Securities as of the close
of business on the Initial Date of Deposit is less than $.975 per
Unit, the purchase orders received on the Initial Date of Deposit
will be filled on the basis of such lower price. Beginning January
30, 1998 the Public Offering Price will be based on value of the
Securities next computed following receipt of the purchase order plus
the applicable sales charge. (See "Valuation").
** No distributions of less than $.0050 per Unit need be made from the
Capital account on any Distribution Date. See "Distributions".
*** This Trust (and therefore the investors) will bear all or a portion
of its organizational costs--including costs of preparing the initial

documents, registering Units with the SEC and the states and the
initial audit of the portfolio--as is common for mutual funds.
Historically, the sponsors of unit investment trusts have paid all
the costs of establishing those trusts.

based upon last dividends actually paid, are expected by the Sponsor
to be sufficient to pay Estimated Expenses of the Trust.

ESSENTIAL INFORMATION REGARDING THE TRUST (CONTINUED)

The Trust. The objective of the PaineWebber Pathfinders Trust, Treasury
and Growth Stock Series
22 (the "Trust") is preservation of capital and capital appreciation through
an investment in the principal or interest portions of stripped "zero-coupon"
United States Treasury notes or bonds as the case may be (the "Treasury
Obligations"), and equity stocks (the "Stock" or "Stocks", and together with
the Treasury Obligations, the "Securities") which, in Sponsor's opinion on
the Initial Date of Deposit, have potential for capital appreciation. The
stripped Treasury Obligations in the Trust portfolio are interest-only
portions of United States Treasury Obligations (as further discussed under
"Risk Factors and Special Considerations"), maturing February 15, 2010 and
which represent approximately 51.6% of the aggregate market value of the
Trust portfolio. The Stocks represent approximately 48.4% of the aggregate
market value of the Trust portfolio. The stripped Treasury Obligations, as
discussed below, make no payment of current interest, but rather make a
single payment upon their stated maturity. Because the maturity value of the
Treasury Obligations is backed by the full faith and credit of the United
States, the Sponsor believes that the Trust provides an attractive
combination of safety and appreciation for purchasers who hold Units until
the Trust's termination. The Trust has been formulated so that the portion of
the Trust invested in stripped Treasury Obligations is designed to provide an
approximate return of principal invested on the Mandatory Termination Date
for purchasers on the Initial Date of Deposit. (See "Essential
Information--Distributions".) Therefore, even if the Stocks are valueless
upon termination of the Trust, and if the Treasury Obligations are held until
their maturity in proportion to the Units outstanding, purchasers will
receive, at the termination of the Trust, $1,000 per 1,000 Units purchased.
This feature of the Trust provides that Unitholders who purchased their units
(the "Units") at or below $1,000 per 1,000 Units and who hold their units to
the Mandatory Termination Date of the Trust on March 2, 2010 will receive the
same amount as they originally invested, although they would have foregone
earning any interest on the amounts involved and will not protect their
principal on a present value basis, assuming the Stocks are valueless.
Therefore, the Trust may be an attractive investment to those persons who buy
their Units during the initial offering period and hold such Units throughout
the life of the Trust until the Trust matures.

Summary of Risk Factors. The stripped Treasury Obligations may appreciate
or depreciate in value depending upon economic and market conditions. (For a
further discussion of stripped Treasury Obligations, see "Risk Factors and
Special Considerations.") The Stock may appreciate or depreciate in value (or
pay dividends) depending on the full range of economic and market influences
affecting corporate profitability, the financial condition of issuers, the
prices of equity securities in general and the Stock in particular and the
risk inherent in an investment made in common stocks in general. Also, the
Trust may contain American Depositary Receipts ("ADRs") which are susceptible
to additional risks, such as foreign currency exchange rate fluctuations, as
well as potential future political and economic developments, which might
adversely affect the payment or receipt of payments on dividends. (See
"Schedule of Investments" to determine if this Trust contains ADRs and "Risk
Factors and Special Considerations" for a further discussion of ADRs.) In
addition, the stripped Treasury Obligations may fluctuate substantially in
value and may be subject to greater fluctuations in value during the life of
the Trust than might be experienced by current interest-bearing Treasury
Obligations which distribute income regularly. There is no assurance that the
Trust's objective will be achieved at the Trust's intended maturity or if the
Trust is terminated or Units redeemed prior to the Trust's intended maturity.
The value of the Securities and, therefore, the value of Units may be
expected to fluctuate. Purchasers who purchase Units subsequent to the
Initial Date of Deposit will receive, if the pro rata portion of the Treasury
Obligations are held until maturity, $1,000 per 1,000 Units as a return of
such purchaser's principal investment, regardless of the purchase price paid
by such purchaser. (See "Risk Factors and Special Considerations.")

<PAGE>
The Composition of the Portfolio. PaineWebber understands the importance of
long-term financial goals such as planning for retirement, funding a child's
education, or trying to build wealth toward some other objective.

In PaineWebber's view, one of the most important investment decisions an
investor faces may be determining how to best allocate his investments to
capture growth opportunities without exposing his portfolio to undue risk.
For long-term capital growth, many investment experts recommend stocks. As
with all investments, the higher return potential of equities is typically
associated with higher risk. With this in mind, PaineWebber designed a
portfolio to meet the needs of investors interested in building wealth
prudently over a long-term time horizon by pairing the security of U.S.
Treasury bonds with the growth potential of equity securities. The Trust is a
balanced portfolio with approximately equal portions in U.S. Treasury bonds
and equity securities. Therefore, should interest rates decline significantly
prior to maturity, there is a potential for achieving greater returns by
liquidating the portfolio before the final maturity date. Unitholders can
sell units at any time at the then current net asset value with no additional
sales charge. (See "Public Offering of Units--Secondary Market for Units and
Redemption".)

The main objective of PaineWebber in constructing the portfolio of stocks
to be included in the Trust was to select a group of stocks which, in
PaineWebber's view, would be capable of, over the long term, closely tracking
the performance of the market as measured by the "S&P 500 Index". The S&P 500
Index is an unmanaged index of 500 stocks the value of which is calculated by
Standard & Poor's Corporation, which index, in PaineWebber's view, is a
broadly diversified, representative segment of the market of all publicly
traded stocks in the United States.

In constructing the Trust's portfolio, a computer program was generated
against the 500 S&P Index stocks to identify a combination of 40 S&P 500
Index stocks (excluding General Electric and those stocks rated
"Unattractive" or "Sell" by PaineWebber Equity Research) which, when equally
weighted, are highly correlated (97%) with the S&P 500 Index within a 3%
tracking error.

The Trust portfolio, in PaineWebber's opinion, is comprised of a
diversified group of large, well-known companies representing various
industries. These are common stocks issued by companies who may receive
income and derive revenues from multiple industry sources but whose primary
source is listed in the table below. For a list of the individual common
stocks comprising each industry group listed below, investors should consult

The Sponsor anticipates that, based upon last dividends actually paid,
dividends from the Stock will be sufficient (i) to pay expenses of the Trust
(see "Expenses of the Trust"), and (ii) after such payment, to make
distributions of such to Unitholders as described below under
"Distributions".

Additional Deposits. After the initial deposit on the Initial Date of
Deposit the Sponsor may, from time to time, cause the deposit of additional
Securities in the Trust where additional Units are to be offered to the
public, replicating the original percentage relationship between the maturity
values of the Treasury Obligations and the number of shares of the Stocks
deposited on the Initial Date of Deposit, subject to certain adjustments. The
Trustee purchases additional securities with cash or cash equivalents based
on instructions to purchase such Securities. Costs incurred in acquiring
additional Stocks which are either not listed on any national securities
exchange or are ADRs, including brokerage fees, stamp taxes and certain other
costs associated with purchasing such additional Stocks, will be borne by the
Trust. Investors purchasing Units during the initial public offering period
will experience a dilution of their investment as a result of the payment of
brokerage fees and other expenses paid by the Trust when the Trustee makes
additional deposits of Securities. (See "The Trust" and "Risk Factors and
Special Considerations".)

Termination. As directed by the Sponsor, approximately 30 days prior to
the maturity of the Treasury Obligations the Trustee will begin to sell the
Stocks held in the Trust. Stocks having the greatest amount of capital
appreciation will be sold first. In certain circumstances, and if there is no
regulatory impediment, monies held upon the sale of Securities may, at the
direction of the Sponsor, be invested for the benefit of Unitholders in
United States Treasury obligations which mature on or prior to the next
distribution date ("Short-Term Treasury Obligations," and together with the
Stocks and the Treasury Obligations, the "Securities") (see "Administration
of the Trust--Reinvestment"). Otherwise, cash received by the Trust upon the
sale or maturity of Securities will be held in non-interest bearing accounts
(created under the Indenture) until distributed and will be of benefit to the
Trustee. During the term of the Trust, Securities will not be sold to take
advantage of market fluctuations. The Trust will terminate within 15 days
after the Treasury Obligations mature. (See "Termination of the Trust and
"Federal Income Taxes".)

Public Offering Price. The Public Offering Price per Unit is computed by
dividing the Trust Fund Evaluation by the number of Units outstanding and
then adding a sales charge of 4.75% of the Public Offering Price (4.99% of
the net amount invested). The sales charge is reduced after the second year
and is also reduced on a graduated scale for sales involving at least $50,000
or 50,000 Units and will be applied on whichever basis is more favorable to
the purchaser. (See "Public Offering of Units--Sales Charge and Volume
Discount".)

The public offering price on the Initial Date of Deposit is determined on
the basis of the value of the Securities as of the close of business on the
preceding business day (i.e., by "backward pricing") under an exemptive order
of the Securities and Exchange Commission (the "SEC"), which applies only to
purchase orders received on the Initial Date of Deposit. As a condition of
that order, however, if the public offering price based on the value of the
Securities as of the close of business on the Initial Date of Deposit (i.e.,
by "forward pricing") would be less than $.975, then purchase orders received
on that day will be filled on the basis of the lower public offering price.

5
<PAGE>

Distributions. The Trustee will distribute any net income and principal
received in excess of $.00500 per Unit quarterly on the Distribution Dates.
(See "Distributions".) Income with respect to the original issue discount on
the Treasury Obligations will not be distributed although Unitholders will be
subject to income tax at ordinary income tax rates as if a distribution had
occurred. (See "Federal Income Taxes".) Upon termination of the Trust, the
Trustee will distribute to each Unitholder his pro rata share of the Trust's
assets, less expenses. The sale of Stocks in the Trust in the period prior to
termination and upon termination may result in a lower amount than might
otherwise be realized if the sale were not required at such time due to
impending or actual termination of the Trust. For this reason, among others,
the amount realized by a Unitholder upon termination of the Trust may be less
than the amount paid by the Unitholder. Unless a Unitholder purchases Units
on the Initial Date of Deposit and unless the Treasury Obligations are
maintained in proportion to the Units created on the Initial Date of Deposit,
total distributions, including distributions made upon termination of the
Trust, may be less than the amount paid for a Unit by a Unitholder.

Market for Units. The Sponsor, though not obligated to do so, presently
intends to maintain a secondary market for Units based upon the value of the
Stocks and the Treasury Obligations as determined by the Trustee as set forth
under "Valuation". The public offering price in the secondary market will be
based upon the value of the Securities next determined after receipt of a
purchase order plus the applicable sales charge. (See "Public Offering of
Units--Public Offering Price" and "Valuation".) If a secondary market is not
maintained, a Unitholder may dispose of his Units only through redemption.
For redemption requests in excess of $100,000, the Sponsor may determine in
its sole discretion to direct the Trustee to redeem units "in kind" by
distributing Securities in lieu of cash to the redeeming Unitholder as
directed by the Sponsor. (See "Redemption".)

TRUST

The Trust is one of a series of similar but separate unit investment
trusts created by the Sponsor under a Trust Indenture and Agreement* (the
"Indenture") dated as of the Initial Date of Deposit, among PaineWebber
Incorporated, as Sponsor and the Investors Bank & Trust Company as Trustee
(the "Trustee"). The objective of the Trust is preservation of capital and
capital appreciation through an investment in Treasury Obligations and
Stocks. These Stocks are equity securities which, in the Sponsor's opinion on
the Initial Date of Deposit, are capable, over the long term, of closely
tracking the performance of the public market for equity securities as
measured by the S&P 500 Index. The Stocks contained in the Trust are
representative of a number of different industries. Dividends received by the
Trust, if any, may be invested in Short-Term Treasury Obligations (if there
is no regulatory impediment). Otherwise, such dividends will be held by the
Trustee in non-interest bearing accounts until used to pay expenses or
distributed to Unitholders on the next Distribution Date and to the extent
that funds are held therein will benefit the Trustee.

On the Initial Date of Deposit, the Sponsor deposited with the Trustee the
confirmations of contracts for the purchase of Securities together with an
irrevocable letter or letters of credit of a commercial bank or banks in an
amount at least equal to the purchase price of the Securities . The value of
the Securities was determined on the basis described under "Valuation". In
exchange for the deposit of the contracts to purchase Securities, the Trustee
delivered to the Sponsor a registered certificate for Units representing the
entire ownership of the Trust. On the Initial Date of Deposit the fractional
undivided interest in the Trust represented by a Unit was as described in
"Essential Information Regarding the Trust".

<PAGE>

With the deposit on the Initial Date of Deposit, the Sponsor established a
proportionate relationship between the maturity value of the Treasury
Obligations and the number of shares of each Stock in the Trust. The Sponsor
may, from time to time, cause the deposit of additional Securities in the
Trust when additional Units are to be offered to the public, replicating the
original percentage relationship between the maturity value of the Treasury
Obligations and the number of shares of Stock deposited on the Initial Date
of Deposit and replicating any cash or cash equivalents held by the Trust
(net of expenses). The original proportionate relationship is subject to
adjustment to reflect the occurrence of a stock split or other corporate
action which affects the capital structure of the issuer of a Stock but which
does not affect the Trust's percentage ownership of the common stock equity
of the issuer at the time of such event. Taxable stock dividends received by
the Trust, if any, will be sold by the Trustee and the proceeds received will
be treated as income to the Trust.

The Treasury Obligations consist of U.S. Treasury obligations which have
been stripped of their unmatured interest coupons or interest coupons
stripped from the U.S. Treasury obligations. The obligor with respect to the
Treasury Obligations is the United States Government. U.S. Government backed
obligations are generally considered the safest investment.

On the Initial Date of Deposit each Unit represented the fractional
undivided interest in the Securities and net income of the Trust set forth
under "Essential Information Regarding the Trust". However, if additional
Units are issued by the Trust (through either the deposit of (i) additional
Securities or (ii) cash for the purchase of additional Securities for
purposes of the sale of additional Units), the aggregate value of Securities
in the Trust will be increased and the fractional undivided interest
represented by each Unit in the balance will be decreased. If any Units are
redeemed, the aggregate value of Securities in the Trust will be reduced, and
the fractional undivided interest represented by each remaining Unit in the
balance will be increased. Units will remain outstanding until redeemed upon
tender to the Trustee by any Unitholder (which may include the Sponsor) or
until the termination of the Trust. (See "Termination of the Trust".)

RISK FACTORS AND SPECIAL CONSIDERATIONS

Risk Factors

An investment in the Trust should be made with the understanding of the
risks inherent in an investment in deep discount or "zero-coupon" debt
obligations and the risks associated with an investment in common stocks in
general.

The Trust contains stripped Treasury securities described below (see
"Schedule of Investments"). Stripped Treasury securities consist of
"interest-only" or "principal-only" portions of Treasury Obligations.
Interest-only portions of Treasury Obligations represent the rights only to
payment of interest on a date certain, and principal-only portions of
Treasury Obligations represent the rights only to payment of principal at a
stated maturity. Interest-only and principal-only portions of Treasury
Obligations are deep discount obligations that are economically identical to
zero-coupon obligations; that is, all such instruments are debt obligations
which make no periodic payment of interest prior to maturity. THE STRIPPED
TREASURY SECURITIES IN THE TRUST WERE PURCHASED AT A DEEP DISCOUNT AND DO NOT
MAKE ANY PERIODIC PAYMENTS OF INTEREST. Instead, the entire payment of
proceeds will be made upon maturity of such Treasury Obligations. The effect
of owning deep discount bonds which do not make current interest payments
(such as the stripped Treasury Obligations in the Trust Portfolio) is that a
fixed yield is earned not only on the original investment but also, in
effect, on all earned discount during the life of the discount obligation.
This implicit reinvestment of earnings at the same rate eliminates the risk
of being unable to reinvest the income on such obligations at a rate as high
as the implicit yield on the discount obligation,

7
<PAGE>

but at the same time eliminates the holder's ability to reinvest at higher
rates in the future. For this reason, while the full faith and credit of the
United States Government provides a high degree of protection against credit
risks, the sale of Units prior to the termination date of the Trust will
involve substantially greater price fluctuations during periods of changing
market interest rates than would be experienced in connection with sale of
Units of a Trust which held Treasury Obligations and which made scheduled
interest payments on a current basis.

An investment in Units of the Trust should also be made with an
understanding of the risks inherent in an investment in common stocks in
general. The general risks are associated with the rights to receive payments
from the issuer of the Stocks, which rights are generally inferior to
creditors of, or holders of debt obligations or preferred stocks issued by,
the issuer. Holders of common stocks have a right to receive dividends only
when and if, and in the amounts, declared by the issuer's board of directors,
and to participate in amounts available for distribution by the issuer only
after all other claims against the issuer have been paid or provided for. By
contrast, holders of preferred stocks have the right to receive dividends at
a fixed rate when and as declared by the issuer's board of directors,
normally on a cumulative basis, but do not participate in other amounts
available for distribution by the issuer. Dividends on cumulative preferred
stock typically must be paid before any dividends are paid on common stock.
Preferred stocks are also entitled to rights on liquidation which are senior
to those of common stocks. For these reasons, preferred stocks generally
entail less risk than common stocks.

Common stocks do not represent an obligation of the issuer. Therefore they
do not offer any assurance of income or provide the degree of protection
offered by debt securities. The issuance of debt securities or preferred
stock by an issuer will create prior claims for payment of principal,
interest and dividends which could adversely affect the ability and
inclination of the issuer to declare or pay dividends on its common stock or
the rights of holders of common stock with respect to assets of the issuer
upon liquidation or bankruptcy. Unlike debt securities which typically have a
stated principal amount payable at maturity, common stocks do not have a
fixed principal amount or a maturity. Additionally, the value of the Stocks
in the Trust, like the Treasury Obligations, may be expected to fluctuate
over the life of the Trust to values higher or lower than those prevailing on
the Date of Deposit. The Stocks may appreciate or depreciate in value (or pay
dividends) depending on the full range of economic and market influences
affecting corporate profitability, the financial condition of issuers and the
prices of equity securities in general and the Stocks in particular.

Certain of the Stocks in the Trust may be ADRs which are subject to
additional risks. (See "Schedule of Investments".) ADRs evidence American
Depositary Shares ("ADS"), which, in turn, represent common stock of foreign
issuers deposited with a custodian in a depositary. (For purposes of this
Prospectus, the term "ADR" generally includes "ADS".) ADRs involve certain
investment risks that are different from those found in Stocks issued by
domestic issuers. These investment risks include potential political and
economic developments, potential establishment of exchange controls, new or
higher levels of taxation, or other governmental actions which might
adversely affect the payment or receipt of payment of dividends on the common
stock of foreign issuers underlying such ADRs. ADRs may also be subject to
current foreign taxes, which could reduce the yield on such securities. Also,
certain foreign issuers are not subject to reporting requirements under U.S.
securities laws and therefore may make less information publicly available
than that provided by domestic issuers. Further, foreign issuers are not
necessarily subject to uniform financial reporting, auditing and accounting
standards and practices which are applicable to publicly traded domestic
issuers.

In addition, the securities underlying the ADRs held in the Trust are
generally denominated, and pay dividends, in foreign currency. An investment
in securities denominated and principally traded in foreign

8
<PAGE>

currencies involves investment risk substantially different than an
investment in securities that are denominated and principally traded in U.S.
dollars. This is due to currency exchange rate risk, because the U.S. dollar
value of the shares underlying the ADRs and of their dividends will vary with
the fluctuations in the U.S. dollar foreign exchange rates for the relevant
currency in which the shares underlying the ADRs are denominated. The Trust,
however, will compute its income in United States dollars, and to the extent
any of the Stocks in the Trust pay income or dividends in foreign currency,
the Trust's computation of income will be made on the date of its receipt by
the Trust at the foreign exchange rate then in effect. PaineWebber observes
that, in the recent past, most foreign currencies have fluctuated widely in
value against the U.S. dollar for many reasons, including the soundness of
the world economy, supply and demand of the relevant currency, and the
strength of the relevant regional economy as compared to the economies of the
United States and other countries. Exchange rate fluctuations are also
dependent, in part, on a number of economic factors including economic
conditions within the relevant country, interest rate differentials between
currencies, the balance of imports and exports of goods and services, and the
transfer of income and capital from one country to another. These economic
factors in turn are influenced by a particular country's monetary and fiscal
policies, perceived political stability (particularly with respect to
transfer of capital) and investor psychology, especially that of
institutional investors, who make assessments of the future relative strength
or weakness of a particular currency. As a general rule, the currency of a
country with a low rate of inflation and a favorable balance of trade should
increase in value relative to the currency of a country with a high rate of
inflation and deficits in the balance of trade.

There is no assurance that the Trust's objective will be achieved. Under
ordinary circumstances, dividends and principal received upon the sale of
Stocks may not be reinvested, and such money will be held in a non-interest
bearing account until the next distribution made on the Distribution Date.
Under certain limited circumstances and if there is no regulatory impediment,
such dividends and principal may be reinvested in Short-Term Treasury
Obligations maturing on or before the next Distribution Date. (See
"Administration of the Trust--Reinvestment".) The value of the Securities
and, therefore, the value of Units may be expected to fluctuate.

Investors should note that the creation of additional Units subsequent to
the Initial Date of Deposit may have an effect upon the value of Units held
by Unitholders. To create additional Units the Sponsor may deposit cash (or
cash equivalents, e.g., a bank letter of credit in lieu of cash) with
instructions to purchase Securities in amounts sufficient to replicate the
original percentage relationship among the Securities based on the price of
the Securities (at the Evaluation Time) on the date the cash is deposited. To
the extent the price of a Security (or the relevant foreign currency exchange
rate, if applicable) increases or decreases between the time cash is
deposited with instructions to purchase the Security and the time the cash is
used to purchase the Security, Units will represent less or more of that
Security and more or less of the other Securities in the Trust. Unitholders
will be at risk because of price (and currency) fluctuations during this
period since if the price of shares of a Security increases, Unitholders will
have an interest in fewer shares of that Security, and if the price of a
Security decreases, Unitholders will have an interest in more shares of that
Security, than if the Security had been purchased on the date cash was
deposited with instructions to purchase the Security. In order to minimize
these effects, the Trust will attempt to purchase Securities as closely as
possible to the Evaluation Time or at prices as close as possible to the
prices used to evaluate the Trust at the Evaluation Time. Thus price (and
currency) fluctuations during this period will affect the value of every
Unitholder's Units and the income per Unit received by the Trust. In
addition, costs incurred in connection with the acquisition of Securities not
listed on any national securities exchange (due to differentials between bid
and offer prices for the Securities) and brokerage fees, stamp taxes and
other costs incurred in purchasing stocks will be at the expense of the Trust
and will affect the value of every Unitholder's Units.

9
<PAGE>
In the event a contract to purchase a Security fails, the Sponsor will
refund to each Unitholder the portion of the sales charge attributable to
such failed contract. Principal and income, if any, attributable to such
failed contract will be distributed to Unitholders of record on the last
business day of the month in which the fail occurs within 20 days of such
record date.

BECAUSE THE TRUST IS ORGANIZED AS A UNIT INVESTMENT TRUST, RATHER THAN AS
A MANAGEMENT INVESTMENT COMPANY, THE TRUSTEE AND THE SPONSOR DO NOT HAVE
AUTHORITY TO MANAGE THE TRUST'S ASSETS FULLY IN AN ATTEMPT TO TAKE ADVANTAGE
OF VARIOUS MARKET CONDITIONS TO IMPROVE THE TRUST'S NET ASSET VALUE, BUT MAY
DISPOSE OF SECURITIES ONLY UNDER LIMITED CIRCUMSTANCES. (SEE "ADMINISTRATION
OF THE TRUST--PORTFOLIO SUPERVISION".)

Certain of the Stocks may be attractive acquisition candidates pursuant to
mergers, acquisitions and tender offers. In general, tender offers involve a
bid by an issuer or other acquiror to acquire a stock based on the terms of
its offer. Payment generally takes the form of cash, securities (typically
bonds or notes), or cash and securities. The Indenture contains provisions
requiring the Trustee to follow certain procedures regarding mergers,
acquisitions, tender offers and other corporate actions. Under certain
circumstances, the Trustee, at the direction of the Sponsor, may hold or sell
any stock or securities received in connection with such corporate actions
(see "Administration of the Trust--Portfolio Supervision").

FEDERAL INCOME TAXES

In the opinion of Carter, Ledyard & Milburn, counsel for the Sponsor,
under existing law:

1. The Trust is not an association taxable as a corporation for federal
income tax purposes. Under the Internal Revenue Code of 1986, as amended
(the "Code"), each Unitholder will be treated as the owner of a pro rata
portion of the Trust, and income of the Trust will be treated as income of
the Unitholder.

2. Each Unitholder will have a taxable event when the Trust disposes of a
Security (whether by sale, exchange, redemption, or payment at maturity)
or when the Unitholder sells its Units or redeems its Units for cash. The
total tax cost of each Unit to a Unitholder is allocated among each of the
Securities in accordance with the proportion of the Trust comprised by
each Security to determine the per Unit tax cost for each Security.

3. The Trust is not an association taxable as a corporation for New York
State income tax purposes. Under New York State law, each Unitholder will
be treated as the owner of a pro rata portion of the Trust and the income
of the Trust will be treated as income of the Unitholders.

The following general discussion of the federal income tax treatment of an
investment in Units of the Trust is based on the Code and United States
Treasury Regulations (established under the Code) as in effect on the date of
this Prospectus. The federal income tax treatment applicable to a Unitholder
may depend upon the Unitholder's particular tax circumstances. The
tax-treatment applicable to non-U.S. investors is not addressed. Future
legislative, judicial or administrative changes could modify the statements
below and could affect the tax consequences to Unitholders. Accordingly, each
Unitholder is advised to consult his or her own tax advisor concerning the
effect of an investment in Units.

General. Each Unitholder must report on its federal income tax return a
pro rata share of the entire income of the Trust, derived from dividends on
Stocks, original issue discount or interest on Treasury Obligations and
Short-Term Treasury Obligations (if any), gains or losses upon dispositions
of Securities by the Trust and a pro rata share of the expenses of the Trust.
Unitholders should note that their taxable income from an investment in Units
will exceed cash distributions because taxable income will include accretions
of original issue discount on the Treasury Obligations.

10
<PAGE>

Distributions with respect to Stock, to the extent they do not exceed
current or accumulated earnings and profits of the distributing corporation,
will be treated as dividends to the Unitholders and will be subject to income
tax at ordinary rates. Corporate Unitholders may be entitled to the
dividends-received deduction discussed below.

To the extent distributions with respect to a Stock were to exceed the
issuing corporation's current and accumulated earnings and profits, they
would not constitute dividends. Rather, they would be treated as a tax free
return of capital and would reduce a Unitholder's tax cost for such Stock.
This reduction in basis would increase any gain, or reduce any loss, realized
by the Unitholder on any subsequent sale or other disposition of Units. After
the tax cost has been reduced to zero, any additional distributions in excess
of current and accumulated earnings and profits would be taxable as gain from
the sale of Stock.

A Unitholder who is an individual, estate or trust may be disallowed
certain itemized deductions described in Code Section 67, including
compensation paid to the Trustee and administrative expenses of the Trust, to
the extent these itemized deductions, in the aggregate, do not exceed two
percent of the Unitholder's adjusted gross income. Thus, a Unitholder's
taxable income from an investment in Units may further exceed amounts
distributed to the extent amounts are used by the Trust to pay expenses.

Corporate Dividends-Received Deduction. Corporate holders of Units may be
eligible for the dividends-received deduction with respect to distributions
treated as dividends, subject to the limitations provided in Sections 246 and
246A of the Code. The dividends-received deduction generally equals 70
percent of the amount of the dividend. As a result, the maximum effective tax
rate on dividends received generally will be reduced from 35 percent to 10.5
percent. A portion of the dividends-received deduction may, however, be
subject to the alternative minimum tax. Individuals, partnerships, trusts, S
corporations and certain other entities are not eligible for the
dividends-received deduction.

Original Issue Discount. The Trust will contain principal or interest
portions of stripped "zero-coupon" Treasury Obligations which are treated as
bonds that were originally issued at a discount ("original issue discount").
Original issue discount represents interest for federal income tax purposes
and can generally be defined as the difference between the price at which a
bond was issued and its stated redemption price at maturity. For purposes of
the preceding sentence, stripped obligations, such as the Treasury
Obligations, which variously consist either of the right to receive payments
of interest or the right to receive payments of principal, are treated by
each successive purchaser as originally issued on their purchase dates at an
issue price equal to their respective purchase prices. The market value of
the assets comprising the Trust will be provided to a Unitholder upon request
to enable the Unitholder to calculate the original issue discount
attributable to each of the Treasury Obligations. Original issue discount on
Treasury Obligations (which were issued or treated as issued on or after July
2, 1982) is deemed earned based on a compounded, constant yield to maturity
over the life of such obligation, taking into account the compounding of
accrued interest at least annually, resulting in an increasing amount of
original issue discount includible in income in each year. Each Unitholder is
required to include in income each year the amount of original issue discount
which accrues on its pro rata portion of each Treasury Obligation with
original issue discount. The amount of accrued original issue discount
included in income for a Unitholder's pro rata interest in Treasury
Obligations is added to the tax cost for such obligations.

Gain or Loss on Sale. If a Unitholder sells or otherwise disposes of a
Unit, the Unitholder generally will recognize gain or loss in an amount equal
to the difference between the amount realized on the disposition allocable to
the Securities and the Unitholder's adjusted tax bases in the Securities. In
general, such adjusted tax bases will equal the Unitholder's aggregate cost
for the Unit increased by any accrued original issue discount. The gain or
loss will be capital gain or loss if the Unit and underlying Securities

<PAGE>

were held as capital assets, except that the gain will be treated as ordinary
income to the extent of any accrued original issue discount not previously
reported. Each Unitholder generally will also recognize taxable gain or loss
when all or part of its pro rata portion of a Security is sold or otherwise
disposed of for an amount greater or less than the Security's per Unit tax
cost.

Withholding For Citizen or Resident Investors. In the case of any
noncorporate Unitholder that is a citizen or resident of the United States a
31 percent "backup" withholding tax will apply to certain distributions of
the Trust unless the Unitholder properly completes and files, under penalties
of perjury, IRS Form W-9 (or its equivalent).

The foregoing discussion is a general summary and relates only to certain
aspects of the federal income tax consequences of an investment in the Trust.
Unitholders may also be subject to state and local taxation. Each Unitholder
should consult its own tax advisor regarding the federal, state and local tax
consequences of ownership of Units.

Investment in the Trust may be suited for purchase by funds and accounts
of individual investors that are exempt from federal income taxes such as
Individual Retirement Accounts, tax-qualified retirement plans including
Keogh Plans, and other tax-deferred retirement plans. Unitholders desiring to
purchase Units for tax-deferred plans and IRA's should consult their
PaineWebber Investment Executive for details on establishing such accounts.
Units may also be purchased by persons who already have self-directed
accounts established under tax-deferred retirement plans.

PUBLIC OFFERING OF UNITS

Public Offering Price. The public offering price per Unit on the Initial
Date of Deposit is equal to the aggregate market value of the Securities
determined on the day preceding the Initial Date of Deposit, divided by the
number of Units outstanding plus the sales charge of 4.75%, pursuant to an
exemptive order of the SEC. However, if the public offering price would be
less than $.975 then purchase orders received that day will be filled on the
basis of the lower public offering price. Thereafter, the public offering
price during the initial offering period will be computed by dividing the
Trust's value (the "Trust Fund Evaluation"), next determined after receipt of
a purchase order, and, with respect to the Treasury Obligations, determined
with reference to the offering side evaluation, by the number of Units
outstanding plus the applicable sales charge. The initial public offering
period will terminate when the Sponsor chooses to discontinue offering Units
in the initial market. Thereafter, the Sponsor may offer Units in the
secondary market. The public offering price in the secondary market will be
the Trust Fund Evaluation per Unit next determined after receipt of a
purchase order, determined for the Treasury Obligations on the bid side of
the market, plus the applicable sales charge. (See "Valuation".) The public
offering price on any date subsequent to the Initial Date of Deposit will
vary from the public offering price calculated on the business day prior to
the Initial Date of Deposit (as described on page 2) due to fluctuations in
the value of Stocks and the Treasury Obligations, and the foreign currency
exchange rates (if applicable), among other factors.

Sales Charge and Volume Discount. The Public Offering Price of Units of
the Trust includes a sales charge which varies based upon the number of Units
purchased by a single purchaser. (See the sales charge schedule below.)
During the initial public offering period, the sales charge will be based on
the number of Trust Units purchased on the same or any preceding day by a
single purchaser. The purchaser or his dealer must notify the Sponsor at the
time of purchase of any previous purchases of Trust Units in order to aggregate
all such purchases and must supply the Sponsor with sufficient information to
permit confirmation of such purchaser's eligibility; acceptance of such
purchase order is subject to confirmation. Purchases of units of other trusts
may not be aggregated with purchases of Trust Units to qualify for this

12
<PAGE>

procedure. This procedure may be amended or terminated at any time without
notice. In the event of such termination, the procedure will revert to that
stated under the sales charge schedule referred to below.

Sales charges during the initial public offering period and for secondary
market sales are described below. A discount in the sales charge is available
to volume purchasers of Units due to economies of scales in sales effort and
sales related expenses relating to volume purchases. The sales charge
applicable to volume purchasers of Units is reduced on a graduated scale for
sales to any person of at least $50,000 or 50,000 Units, applied on whichever
basis is more favorable to the purchaser.

The volume discount sales charge shown above will apply to all purchases
of Units on any one day by the same person in the amounts stated above, and
for this purpose purchases of Units of this Trust will be aggregated with
concurrent purchases of any other trust which may be offered by the Sponsor.
Units held in the name of the purchaser's spouse or in the name of a
purchaser's child under the age of 21 are deemed for the purposes of
calculating the reduced sales charge to be registered in the name of the
purchaser. The reduced sales charges are also applicable to a trustee or
other fiduciary purchasing Units for a single trust estate or single
fiduciary account.

Employee Discount. Due to the realization of economies of scale in sales
effort and sales related expenses for the purchase of Units by employees of
the Sponsor and its affiliates, the Sponsor intends to permit employees of
the Sponsor and its affiliates and certain of their relatives to purchase
units of the Trust at a reduced sales charge of $5.00 per 1,000 Units.

Exchange Option. Unitholders may elect to exchange any or all of their
Units of this series for units of one or more of any series of PaineWebber
unit investment trusts (the "Exchange Option") including the following: The
PaineWebber Municipal Bond Fund (the "PaineWebber Series"); The Municipal
Bond Trust (the "National Series"); The Municipal Bond Trust, Multi-State
Program (the "Multi-State Series"); The Municipal Bond Trust, California
Series (the "California Series"); The Corporate Bond Trust (the "Corporate
Series"); PaineWebber Pathfinder's Trust (the "Pathfinder's Trust"); the
PaineWebber Federal Government Trust (the "Government Series"); The Municipal
Bond Trust, Insured Series (the "Insured Series"); or the PaineWebber Equity
Trust (the "Equity Series") (collectively referred to as the "Exchange
Trusts"), at a Public Offering Price for the units of the Exchange Trusts to
be acquired based on a reduced sales charge of $15 per unit, per 100 units in
the case of a trust whose units cost approximately $10 or per 1,000 units in
the case of a trust whose units cost approximately one dollar. Unitholders of
this Trust are not eligible for the Exchange Option into an Equity Trust,
Growth Stock Series that is designated as a rollover series for the 30 day
period prior to termination of the Trust. The purpose of such reduced sales
charge is to permit the Sponsor to pass on to the Unitholder who wishes to
exchange Units the cost savings resulting from the exchange of Units. The
cost savings result from reductions in time and expense related to advice,
financial planning and operational expenses required for the Exchange Option.
Each Exchange Trust has different investment objectives, therefore a
Unitholder should read the prospectus for the applicable exchange trust
carefully prior to exercising this option. Exchange Trusts having as their
objective the receipt of tax-exempt interest income would not be suitable for
tax-deferred investment plans such as Individual Retirement Accounts. A
Unitholder who purchased units of a series and paid a per unit, per 100 unit
or per 1,000 unit sales charge that was less than the per unit, per 100 unit
or per 1,000 unit sales charge of the series of the Exchange Trusts for which
such Unitholder desires to exchange into, will be allowed to exercise the
Exchange Option at the unit offering price plus the reduced sales charge,
provided the Unitholder has held the units for at least five months. Any such
Unitholder who has not held the units to be exchanged for the five-month
period will be required to exchange them at the unit offering price plus a
sales charge based on the greater of the reduced sales charge, or an amount
which, together with the initial sales charge paid in connection with the
acquisition of the Units being exchanged, equals the sales charge of the
series of the Exchange Trust for which such Unitholder desires to exchange
into, determined as of the date of the exchange.

The Sponsor will permit exchanges at the reduced sales charge provided
there is either a primary market for Units or a secondary market maintained
by the Sponsor in both the Units of this series and units of the applicable
Exchange Trust and there are units of the applicable Exchange Trust available
for sale. While the Sponsor has indicated that it intends to maintain a
market for the Units of the respective Trusts, there is no obligation on its
part to maintain such a market. Therefore, there is no assurance that

14
<PAGE>

a market for Units will in fact exist on any given date at which a Unitholder
wishes to sell his Units of this series and thus there is no assurance that
the Exchange Option will be available to a Unitholder. Exchanges will be
effected in whole Units only. Any excess proceeds from Unitholders' Units
being surrendered will be returned. Unitholders will be permitted to advance
new money in order to complete an exchange to round up to the next highest
number of Units. An exchange of Units under the Exchange Option will normally
constitute a "taxable event" under the Code and a Unitholder will generally
recognize a tax gain or loss at the time of exchange in the same manner as
upon a sale of Units. Unitholders are urged to consult their own tax advisors
as to the tax consequences of exchanging Units.

The Sponsor reserves the right to modify, suspend or terminate the
Exchange Option at any time without further notice to Unitholders. In the
event the Exchange Option is not available to a Unitholder at the time he
wishes to exercise it, the Unitholder will be immediately notified and no
action will be taken regarding the exchange of Units without further
instruction from the Unitholder.

To exercise the Exchange Option, a Unitholder should notify the Sponsor of
his desire to exercise the Exchange Option and to use the proceeds from the
sale of his Units to the Sponsor of this series to purchase units of one or
more of the Exchange Trusts from the Sponsor. If units of the applicable
outstanding series of the Exchange Trust are at that time available for sale,
and if such units may lawfully be sold in the state in which the Unitholder
is resident, the Unitholder may select the series or group of series for
which he desires his investment to be exchanged. The Unitholder will be
provided with a current prospectus or prospectuses relating to each series in
which he indicates interest.

The exchange transaction will operate in a manner essentially identical to
any secondary market transaction, i.e., Units will be repurchased at a price
based on the market value of the Securities in the portfolio of the Trust
next determined after receipt by the Sponsor of an exchange request and
properly endorsed Certificate, if any, for Units. Units of the Exchange Trust
will be sold to the Unitholder at a price based upon the next determined
market value of the securities in the Exchange Trust plus the reduced sales
charge. Exchange transactions will be effected only in whole units; thus, any
proceeds not used to acquire whole units will be paid to the selling
Unitholder.

For example, assume that a Unitholder, who has three thousand units of a
trust with a current price of $1.30 per unit, desires to sell his units and
seeks to exchange the proceeds for units of a series of an Exchange Trust
with a current price of $890 per unit based on the bid prices of the
underlying securities. In this example, which does not contemplate any
rounding up to the next highest number of units, the proceeds from the
Unitholder's units would aggregate $3,900. Since only whole units of an
Exchange Trust may be purchased under the Exchange Option, the Unitholder
would be able to acquire four units in the Exchange Trust for a total cost of
$3,620 ($3,560 for the units and $60 for the sales charge). If all 3,000
units were tendered, the remaining $280 would be returned to the Unitholder.

Conversion Option. Owners of units of any registered unit investment trust
sponsored by another sponsor which was initially offered at a maximum
applicable sales charge of at least 3.0% (a "Conversion Trust") may elect to
apply the cash proceeds of the sale or redemption of those units directly to
acquire available units of any Exchange Trust at a reduced sales charge of
$15 per unit (or per 100 units in the case of Exchange Trusts having a unit
price of approximately $10, or per 1,000 units in the case of Exchange Trusts
having a unit price of approximately $1), subject to the terms and conditions
applicable to the Exchange Option (except that no secondary market is
required for Conversion Trust units). To exercise this option, the owner
should notify his retail broker. He will be given a prospectus for each
series in which he indicates interest and for which units are available. The
dealer must sell or redeem the units of the Conversion Trust. Any dealer
other than PaineWebber must certify that the purchase of units of the

15
<PAGE>

Exchange Trust is being made pursuant to and is eligible for the Conversion
Option. The dealer will be entitled to two thirds of the applicable reduced
sales charge. The Sponsor reserves the right to modify, suspend or terminate
the Conversion Option at any time without further notice, including the right
to increase the reduced sales charge applicable to this conversion option
(but not in excess of $5 more per Unit (or per 100 Units or per 1,000 Units,
as applicable) than the corresponding fee then being charged for the Exchange
Option). For a description of the tax consequences of a conversion, please
refer to the Exchange Option section of this Prospectus.

Distribution of Units. The minimum purchase during the initial public
offering is $250. Only whole Units may be purchased.

The Sponsor is the sole underwriter of the Units. Sales may, however, be
made to dealers who are members of the National Association of Securities
Dealers, Inc. ("NASD") at prices which include a concession of $.03 per Unit,
during the initial offering period and one-half of the highest applicable
sales charge during the secondary market, subject to change from time to
time. The difference between the sales charge and the dealer concession will
be retained by the Sponsor. In the event that the dealer concession is 90% or
more of the sales charge per Unit, dealers taking advantage of such
concession may be deemed to be underwriters under the Securities Act of 1933,
as amended (the "Securities Act").

The Sponsor reserves the right to reject, in whole or in part, any order
for the purchase of Units. The Sponsor intends to qualify the Units in all
states of the United States, the District of Columbia and the Commonwealth of
Puerto Rico.

Secondary Market for Units. While not obligated to do so, the Sponsor
intends to maintain a secondary market for the Units and continuously offer
to purchase Units at the Trust Fund Evaluation per Unit next computed after
receipt by the Sponsor of an order from a Unitholder. The Sponsor may cease
to maintain a market at any time, and from time to time, without notice. In
the event that a secondary market for the Units is not maintained by the
Sponsor, a Unitholder desiring to dispose of Units may tender Units to the
Trustee for redemption, at the price calculated in the manner described under
"Redemption". Redemption requests in excess of $100,000 may be redeemed "in
kind" as described under "Redemption." The Sponsor does not in any way
guarantee the enforceability, marketability, value or price of any Stocks in
the Trust, nor that of the Units.

Investors should note the Trust Fund Evaluation per Unit at the time of
sale or tender for redemption may be less than the price at which the Unit
was purchased.

The Sponsor may redeem any Units it has purchased in the secondary market
if it determines for any reason that it is undesirable to continue to hold
these Units in its inventory. Factors which the Sponsor may consider in
making this determination will include the number of units of all series of
all trusts which it holds in its inventory, the saleability of the Units, its
estimate of the time required to sell the Units and general market
conditions.

Sponsor's Profits. In addition to the applicable sales charge, the Sponsor
realizes a profit (or sustains a loss) in the amount of any difference
between the cost of the Securities to the Sponsor and the price (including
foreign currency rates, if any) at which it deposits the Securities in the
Trust, which is the value of the Securities, determined by the Trustee as
described under "Valuation" at the close of business on the business day
prior to the Initial Date of Deposit. The cost of Securities to the Sponsor
includes the amount paid by the Sponsor for brokerage commissions. These
amounts are an expense of the Trust.

Cash, if any, received from Unitholders prior to the settlement date for
the purchase of Units or prior to the payment for Securities upon their
delivery may be used in the Sponsor's business subject to the limitations of
Rule 15c3-3 under the Securities and Exchange Act of 1934, as amended and may
be of benefit to the Sponsor.

16
<PAGE>
In selling any Units in the initial public offering after the Initial Date
of Deposit, the Sponsor may realize profits or sustain losses resulting from
fluctuations in the net asset value of outstanding Units during that period.
In maintaining a secondary market for the Units, the Sponsor may realize
profits or sustain losses in the amount of any differences between the price
at which it buys Units and the price at which it resells or redeems such
Units.

REDEMPTION

Units may be tendered to the Trustee, Investors Bank & Trust Company, for
redemption at its office in person, or by mail at Hancock Towers, P.O. Box
9130, Boston, MA 02117-9130 upon payment of any transfer or similar tax which
must be paid to effect the redemption. At the present time there are no such
taxes. No redemption fee will be charged by the Sponsor or the Trustee. If
Units are represented by a certificate, it must be properly endorsed
accompanied by a letter requesting redemption. If held in uncertificated
form, a written instrument of redemption must be signed by the Unitholder.
Unitholders must sign exactly as their names appear on the records of the
Trustee with signatures guaranteed by an eligible guarantor institution or in
such other manner as may be acceptable to the Trustee. In certain instances
the Trustee may require additional documents such as, but not limited to,
trust instruments, certificates of death, appointments as executor or
administrator, or certificates of corporate authority. Unitholders should
contact the Trustee to determine whether additional documents are necessary.
Units tendered to the Trustee for redemption will be cancelled if not
repurchased by the Sponsor.

Units will be redeemed at the redemption value per Unit (the "Redemption
Value") next determined after receipt of the redemption request in good order
by the Trustee. The Redemption Value per Unit is determined by dividing the
Trust Fund Evaluation by the number of Units outstanding. (See "Valuation.")

A redemption request is deemed received on the business day (See
"Valuation" for a definition of business day) when such request is received
prior to 4:00 p.m. If it is received after 4:00 p.m., it is deemed received
on the next business day. During the period in which the Sponsor maintains a
secondary market for Units, the Sponsor may repurchase any Unit presented for
tender to the Trustee for redemption no later than the close of business on
the second business day following such presentation and Unitholders will
receive the Redemption Value next determined after receipt by the Trustee of
the redemption request. Proceeds of a redemption will be paid to the
Unitholder on the seventh calendar day following the date of tender (or if
the seventh calendar day is not a business day on the first business day
prior to the seventh calendar day).

With respect to cash redemptions, amounts representing income received
shall be withdrawn from the Income Account, and, to the extent such balance
is insufficient, from the Capital Account. The Trustee is empowered, to the
extent necessary, to sell Securities in the manner as is directed by the
Sponsor, which direction will be given to maximize the objectives of the
Trust. In the event that no such direction is given by the Sponsor, the
Trustee is empowered to sell Securities as follows: Treasury Obligations will
be sold to maintain in the Trust Treasury Obligations in an amount which,
upon maturity, will equal at least $1.00 per Unit outstanding after giving
effect to such redemption and Stocks having the greatest amount of capital
appreciation will be sold first. (See "Administration of the Trust".)
However, with respect to redemption requests in excess of $100,000, the
Sponsor may determine in its discretion to direct the Trustee to redeem Units
"in kind" by distributing Securities to the redeeming Unitholder. When Stock
is distributed, a proportionate amount of Stock will be distributed, rounded
to avoid the distribution of fractional shares and using cash or checks where
rounding is not possible. The Sponsor may direct the Trustee to redeem Units
"in kind" even if it is then maintaining a secondary market in Units of the
Trust.

17
<PAGE>

Securities will be valued for this purpose as set forth under "Valuation". A
Unitholder receiving a redemption "in kind" may incur brokerage or other
transaction costs in converting the Securities distributed into cash. The
availability of redemption "in-kind" is subject to compliance with all
applicable laws and regulations, including the Securities Act.

To the extent that Securities are redeemed in kind or sold, the size and
diversity of the Trust will be reduced. Sales will usually be required at a
time when Securities would not otherwise be sold and may result in lower
prices than might otherwise be realized. The price received for Units upon
redemption may be more or less than the amount paid by the Unitholder
depending on the value of the Securities in the portfolio at the time of
redemption. In addition, because of the minimum amounts in which Securities
are required to be sold, the proceeds of sale may exceed the amount required
at the time to redeem Units; these excess proceeds will be distributed to
Unitholders on the Distribution Dates.

The Trustee may, in its discretion, and will, when so directed by the
Sponsor, suspend the right of redemption, or postpone the date of payment of
the Redemption Value, for more than seven calendar days following the day of
tender for any period during which the New York Stock Exchange, Inc. is
closed other than for weekend and holiday closings; or for any period during
which the SEC determined that trading on the New York Stock Exchange, Inc. is
restricted or for any period during which an emergency exists as a result of
which disposal or evaluation of the Securities is not reasonably practicable;
or for such other period as the SEC may by order permit for the protection of
Unitholders. The Trustee is not liable to any person or in any way for any
loss or damages which may result from any suspension or postponement, or any
failure to suspend or postpone when done in the Trustee's discretion.

VALUATION

The Trustee will calculate the Trust Fund Evaluation per Unit at the
Evaluation Time described under "Essential Information Regarding the Trust"
(1) on each June 30 and December 31 (or the last business day prior thereto),
(2) on each business day as long as the Sponsor is maintaining a bid in the
secondary market, (3) on the business day on which any Unit is tendered for
redemption and (4) on any other day desired by the Sponsor or the Trustee, by
adding (a) the aggregate value of the Securities and other assets determined
by the Trustee as described below, (b) cash on hand in the Trust, income
accrued on the Treasury Obligations but not distributed or held for
distribution and dividends receivable on Stocks trading ex-dividend (other
than any cash held in any reserve account established under the Indenture)
and (c) accounts receivable for Securities sold and any other assets of the
Trust Fund not included in (a) and (b) above and deducting therefrom the sum
of (v) taxes or other governmental charges against the Trust not previously
deducted, (w) accrued fees and expenses of the Trustee and the Sponsor
(including legal and auditing expenses) and other Trust expenses, (x) cash
allocated for distribution to Unitholders, and (y) accounts payable for Units
tendered for redemption and any other liabilities of the Trust Fund not
included in (v), (w), (x) and (y) above. The Trust Fund Evaluation per Unit
is calculated by dividing the result of the above computation by the number
of Units outstanding as of the date of the Trust Fund Evaluation. Business
days do not include Saturdays, Sundays, New Year's Day, Martin Luther King,
Jr. Day, President's Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day and Christmas Day and other days that the New York
Stock Exchange is closed. The U.S. dollar value of Stock denominated in
foreign currency, if any, contained in the Trust, will be based on the
applicable foreign currency exchange rate calculated at the Evaluation Time.

The value of Stocks will be determined by the Trustee in good faith in the
following manner: (1) if the Securities are listed on one or more national
securities exchanges, the evaluation will be based on the closing sale price
on that day (unless the Trustee deems such price inappropriate as a basis for
evaluation)

18
<PAGE>

on the exchange which is the principal market for the Stock (deemed to be the
New York Stock Exchange if the Securities are listed thereon) (2) if there is
no such appropriate closing sale price on such exchange, at the mean between
the closing bid and asked prices on such exchange (unless the Trustee deems
such price inappropriate as a basis for evaluation), (3) if the Stocks are
not so listed or, if so listed and the principal market for the Stock is
other than on such exchange or there are no such appropriate closing bid and
asked prices available, such evaluation shall be made by the Trustee in good
faith based on the closing sale price on the over-the-counter market (unless
the Trustee deems such price inappropriate as a basis for evaluation) or (4)
if there is no such appropriate closing price, then (a) on the basis of
current bid prices, (b) if bid prices are not available, on the basis of
current bid prices for comparable securities, (c) by the Trustee's appraising
the value of the Securities in good faith on the bid side of the market or
(d) by any combination of the above.

During the initial offering period the Treasury Obligations are valued on
the basis of offering prices; thereafter and for purposes of determining the
Redemption Value they are valued on the basis of bid prices. The aggregate
offering and bid prices of the Treasury Obligations are the prices obtained
from investment dealers or brokers (which may include the Sponsor) who
customarily deal in Treasury Obligations; or, if there is no market for the
Treasury Obligations, and bid or offering prices are not available, on the
basis of current bid or offering prices for comparable securities; or by
appraisal; or by any combination of the above, adjusted to reflect income
accrued.

COMPARISON OF PUBLIC OFFERING PRICE AND REDEMPTION VALUE

While the Public Offering Price of Units during the initial offering
period is determined on the basis of the current offering prices of the
Treasury Obligations, the Public Offering Price of Units in the secondary
market and the Redemption Value is determined on the basis of the current bid
prices of the Treasury Obligations. The Stocks are valued on the same basis
for the initial and secondary markets and for purposes of redemptions. On the
business day prior to the Date of Deposit, the Public Offering Price per Unit
(which figure includes the sales charge) exceeded the Redemption Value, (See
"Essential Information"). The bid and offering prices of the Treasury
Obligations is expected to vary. For this reason and others, including the
fact that the Public Offering Price includes the sales charge, the amount
realized by a Unitholder upon redemption of Units may be less than the price
paid by the Unitholder for the Units.

EXPENSES OF THE TRUST

The cost of the preparation of the Certificates, the Indenture and this
Prospectus, the initial fees of the Trustee and the Trustee's counsel, and
certain expenses incurred in establishing the Trust including legal and
auditing fees and initial SEC and state registration fees (the
"Organizational Expenses"), will be paid by the Trust, as is common for
mutual funds. Historically, the Sponsors of unit investment trusts have paid
all organizational expenses. The Sponsor will receive no fee from the Trust
for its services in establishing the Trust.

The Sponsor will receive a fee, which is earned for portfolio supervisory
services, and which is based upon the largest number of Units outstanding
during the calendar year. The Sponsor's fee, which is initially $.00035 per
Unit, may exceed the actual costs of providing portfolio supervisory services
for the Trust, but at no time will the total amount it receives for portfolio
supervisory services rendered to all series of the PaineWebber Pathfinders
Trust in any calendar year exceed the aggregate cost to it of supplying such
services in such year.

For its services as Trustee and Evaluator, the Trustee will be paid in
monthly installments, at an annual rate of $.00145 per Unit computed monthly
based upon the largest number of Units outstanding

19
<PAGE>

in the Trust during the preceding month. In addition, the regular and
recurring expenses of the Trust are estimated to be $.00155 per Unit annually
which include, but are not limited to Organizational Expenses of $.00080 per
Unit and certain mailing, printing, and audit expenses. Expenses in excess of
this estimate will be borne by the Trust. The Trustee could also benefit to
the extent that it may hold funds in non-interest bearing accounts created
under the Indenture.

The Sponsor's fee and Trustee's fee may be increased without approval of
the Unitholders by an amount not exceeding a proportionate increase in the
category entitled "All Services Less Rent" in the Consumer Price Index
published by the United States Department of Labor or if the Consumer Price
Index is no longer published, a similar index as determined by the Trustee
and Sponsor.

In addition to the above, the following charges are or may be incurred by
the Trust and paid from the Income Account, or, to the extent funds are not
available in the Income Account, from the Capital Account (see
"Administration of the Trust-Accounts"): (1) fees for the Trustee for
extraordinary services; (2) expenses of the Trustee (including legal and
auditing expenses) and of counsel; (3) various governmental charges; (4)
expenses and costs of any action taken by the Trustee to protect the Trust
and the rights and interests of the Unitholders; (5) indemnification of the
Trustee for any loss, liabilities or expenses incurred by it in the
administration of the Trust without gross negligence, bad faith or wilful
misconduct on its part; (6) brokerage commissions and other expenses incurred
in connection with the purchase and sale of Securities; and (7) expenses
incurred upon termination of the Trust. In addition, to the extent then
permitted by the SEC, the Trust may incur expenses of maintaining
registration or qualification of the Trust or the Units under Federal or
state securities laws so long as the Sponsor is maintaining a secondary
market (including, but not limited to, legal, auditing and printing
expenses).

The accounts of the Trust shall be audited not less than annually by
independent auditors selected by the Sponsor. The expenses of the audit shall
be an expense of the Trust. So long as the Sponsor maintains a secondary
market, the Sponsor will bear any audit expense which exceeds $.00050 per
Unit. Unitholders covered by the audit during the year may receive a copy of
the audited financial statements upon request.

The fees and expenses described above are payable out of the Trust and
when unpaid will be secured by a lien on the Trust. Based upon the last
dividend paid prior to the Initial Date of Deposit, dividends on the Stocks
are expected to be sufficient to pay the estimated expenses of the Trust. To
the extent that dividends paid with respect to the Stocks are not sufficient
to meet the expenses of the Trust, the Trustee is authorized to sell
Securities in the same manner as provided in "Redemption" herein.

RIGHTS OF UNITHOLDERS

Ownership of Units is evidenced by recordation on the books of the
Trustee. In order to avoid additional operating costs and for investor
convenience, certificates will not be issued unless a request, in writing
with signature guaranteed by an eligible guarantor institution or in such
other manner as may be acceptable to the Trustee, is delivered by the
Unitholder to the Sponsor. Issued Certificates are transferable by
presentation and surrender to the Trustee at its office in Boston,
Massachusetts properly endorsed or accompanied by a written instrument or
instruments of transfer. Uncertificated Units are transferable by
presentation to the Trustee at its office of a written instrument of
transfer.

Certificates may be issued in denominations of one Unit or any integral
multiple of one Unit as deemed appropriate by the Trustee. A Unitholder may
be required to pay $2.00 per certificate reissued or transferred, and shall
be required to pay any governmental charge that may be imposed in connection
with each transfer or interchange. For new certificates issued to replace
destroyed, mutilated, stolen

20
<PAGE>

or lost certificates, the Unitholder must furnish indemnity satisfactory to
the Trustee and must pay any expenses that the Trustee may incur. Mutilated
certificates must be surrendered to the Trustee for replacement.

DISTRIBUTIONS

The Trustee will distribute any net income received, if any, from the
Income Account, quarterly on the Distribution Dates to Unitholders of record
on the preceding Record Date. Income with respect to the original issue
discount on the Treasury Obligations will not be distributed although
Unitholders will be subject to tax as if a distribution had occurred.
Distributions from the Capital Account will be made on quarterly Distribution
Dates to Unitholders of record on the preceding Record Date, provided
however, that distributions of less than $.00500 per Unit need not be made
from the Capital Account on any Distribution Date. See "Federal Income
Taxes".

Within a reasonable period after the Trust is terminated, each Unitholder
will, upon surrender of his Certificates for cancellation, receive his pro
rata share of the amounts realized upon disposition of the Securities plus
any other assets of the Trust, less expenses of the Trust. (See
"Termination.")

ADMINISTRATION OF THE TRUST

Accounts. All dividends received and interest, if any, accrued on
Securities, proceeds from the sale of Securities or other monies received by
the Trustee on behalf of the Trust shall be held in trust in Short-Term
Treasury Obligations (if permissible) or in non-interest bearing accounts
until required to be disbursed.

The Trustee will credit on its books to the Income Account any dividends
(including stock dividends which were sold) and interest, if any, accrued by
the Trust. All other receipts (i.e. return of principal, and gains) are
credited on its books to a Capital Account. Stock dividends received by the
Trust, if any, will be sold by the Trustee and the proceeds therefrom be
treated as income to the Trust. A record will be kept of qualifying dividends
within the Income Account. The pro rata share of the Income Account and the
pro rata share of the Capital Account represented by each Unit will be
computed by the Trustee as set forth under "Valuation".

The Trustee will deduct from the Income Account and, to the extent funds
are not sufficient in the Income Account, from the Capital Account, amounts
necessary to pay expenses incurred by the Trust. (See "Expenses and
Charges.") In addition, the Trustee may withdraw from the Income Account and
the Capital Account any amounts that may be necessary to cover redemption of
Units by the Trustee. (See "Redemption.")

The Trustee may establish reserves (the "Reserve Account") within the
Trust for state and local taxes, if any, and any other governmental charges
payable out of the Trust.

Reports and Records. With the distribution of income from the Trust,
Unitholders will be furnished with a statement setting forth the amount being
distributed from each account.

The Trustee keeps records and accounts of the Trust at its office in
Boston, including records of the names and addresses of Unitholders, a
current list of underlying Securities in the portfolio and a copy of the
Indenture. Records pertaining to a Unitholder or to the Trust (but not to
other Unitholders) are available to the Unitholder for inspection at
reasonable times during business hours.

Within a reasonable period of time after the end of each calendar year,
starting with calendar year 1998, the Trustee will furnish each person who
was a Unitholder at any time during the calendar year an annual report
containing the following information, expressed in reasonable detail both as
a dollar

21
<PAGE>

amount and as a dollar amount per Unit: (1) a summary of transactions for the
year in the Income, Capital and Reserve Accounts; (2) any Securities sold
during the year and the Securities held at the end of the year; (3) the Trust
Fund Evaluation per Unit, computed as of the 31st day of December of such
year (or the last business day prior thereto); and (4) amounts distributed to
Unitholders during such year.

Portfolio Supervision. The portfolio of the Trust is not "managed" by the
Sponsor or the Trustee; their activities described in this Prospectus are
governed solely by the provisions of the Indenture. The Indenture provides
that the Sponsor may (but need not) direct the Trustee to dispose of a
Security (or tender a Security for cash in the case of paragraph (6) below):

(1) upon the failure of the issuer to declare or pay anticipated
dividends or interest;

(2) upon the institution of materially adverse action or proceeding at
law or in equity seeking to restrain or enjoin the declaration or payment
of dividends or interest on any such Securities or the existence of any
other materially adverse legal question or impediment affecting such
Securities or the declaration or payment of dividends or interest on the
same;

(3) upon the breach of covenant or warranty in any trust indenture or
other document relating to the issuer which might materially and
adversely affect either immediately or contingently the declaration or
payment of dividends or interest on such Securities;

(4) upon the default in the payment of principal or par or stated value
of, premium, if any, or income on any other outstanding securities of the
issuer or the guarantor of such securities which might materially and
adversely, either immediately or contingently, affect the declaration or
payment of dividends or interest on the Securities;

(5) upon the decline in price or the occurrence of any materially
adverse market or credit factors, that in the opinion of the Sponsor,
make the retention of such Securities not in the best interest of the
Unitholder;

(6) upon a public tender offer being made for a Security, or a merger or
acquisition being announced affecting a Security that in the opinion of
the Sponsor make the sale or tender of the Security in the best interests
of the Unitholders;

(7) upon a decrease in the Sponsor's internal rating of the Security; or

(8) upon the happening of events which, in the opinion of the Sponsor,
negatively affect the economic fundamentals of the issuer of the Security
or the industry of which it is a part.

The Indenture contains certain instructions to the Trustee regarding
corporate actions that affect Securities held in the Trust. In most cases,
the Trustee is required to use its best efforts to vote the Securities as
closely as practicable in the same manner and in the same proportion as are
all other securities held by owners other than the Trust. In cases of offers
to exchange Securities for other stock or securities (including but not
limited to a tender offer), the Trustee is required to reject such offers.
If, after complying with such procedures, the Trustee nevertheless receives
stock or securities, with or without cash, as a result of the corporate
action, the Trustee, at the direction of the Sponsor, may retain or sell the
stock or securities. Any stock or securities so retained will be subject to
the terms and conditions of the Indenture to the same extent as the
Securities originally deposited in the Trust.

The Trustee may dispose of Securities where necessary to pay Trust
expenses or to satisfy redemption requests as directed by the Sponsor and in
a manner necessary to maximize the objectives of the Trust, or if not so
directed in its own discretion, provided however, that Treasury Obligations
will be sold to

22
<PAGE>

maintain in the Trust Treasury Obligations in an amount which, upon maturity,
will equal at least $1.00 per Unit outstanding after giving effect to the
redemption and Stocks having the greatest appreciation shall be sold first.

Reinvestment. Cash received upon the sale of Stock (except for sales to
meet redemption requests) and dividends received may, if and to the extent
there is no legal or regulatory impediment, be reinvested in Short-Term
Treasury Obligations. The Sponsor anticipates that, where permitted, such
proceeds will be reinvested in interest bearing Short-Term Treasury
Obligations unless factors exist such that reinvestment would not be in the
best interest of Unitholders or would be impractical. Such factors may
include, among others, (i) short reinvestment periods which would make
reinvestment in Short-Term Treasury Obligations undesirable or infeasible and
(ii) amounts not sufficiently large so as to make a reinvestment economical
or feasible. Any moneys held and not reinvested will be held in a
non-interest bearing account until distribution on the next Distribution Date
to Unitholders of record.

AMENDMENT OF THE INDENTURE

The Indenture may be amended by the Trustee and the Sponsor without the
consent of any of the Unitholders to cure any ambiguity or to correct or
supplement any provision of the Indenture which may be defective or
inconsistent or to make other provisions that will not materially adversely
affect the interest of the Unitholders.

The Indenture may be amended in any respect by the Sponsor and the Trustee
with the consent of the holders of 51% of the Units then outstanding;
provided that no such amendment shall (1) reduce the interest in the Trust
represented by a Unit or (2) reduce the percentage of Unitholders required to
consent to any such amendment, without the consent of all Unitholders.

The Trustee will promptly notify Unitholders of the substance of any
amendment affecting Unitholders rights or their interest in the Trust.

TERMINATION OF THE TRUST

The Indenture provides that the Trust will terminate within 15 days after
the maturity of the Treasury Obligations held in the Trust. If the value of
the Trust as shown by the Trust Fund Evaluation is less than twenty percent
(20%) of the market value of the Securities on the Date of Deposit, the
Trustee may in its discretion, and will when so directed by the Sponsor,
terminate the Trust. The Trust may also be terminated at any time by the
written consent of 51% of the Unitholders or by the Trustee upon the
resignation or removal of the Sponsor if the Trustee determines termination
to be in the best interest of the Unitholders. In no event will the Trust
continue beyond the Mandatory Termination Date as stated in "Essential
Information Regarding the Trust."

As directed by the Sponsor approximately 30 days prior to the maturity of
the Treasury Obligations the Trustee will begin to sell the Stocks held in
the Trust. Stocks having the greatest amount of capital appreciation will be
sold first. Upon termination of the Trust, the Trustee will sell any Stocks
then remaining in the Trust and will then, after deduction of any fees and
expenses of the Trust and payment into the Reserve Account of any amount
required for taxes or other governmental charges that may be payable by the
Trust, distribute to each Unitholder, upon surrender for cancellation of his
Certificate (if applicable) after due notice of such termination, such
Unitholder's pro rata share in the Income and Capital Accounts. Monies held
upon the sale of Securities will be held in Short-Term Treasury Obligations
(if permissible) or in non-interest bearing accounts created under the
Indenture until distributed and, if not re-invested, will be of benefit to
the Trustee. The sale of Stocks in the Trust in the period prior to

23
<PAGE>

termination and upon termination may result in a lower amount than might
otherwise be realized if the sale were not required at such time due to
impending or actual termination of the Trust. For this reason, among others,
the amount realized by a Unitholder upon termination may be less than the
amount paid by the Unitholder.

SPONSOR

The Sponsor, PaineWebber Incorporated, is a corporation organized under
the laws of the State of Delaware. The Sponsor is a member firm of the New
York Stock Exchange, Inc. as well as other major securities and commodities
exchanges and is a member of the National Association of Securities Dealers,
Inc. The Sponsor is engaged in a security and commodity brokerage business as
well as underwriting and distributing new issues. The Sponsor also acts as a
dealer in unlisted securities and municipal bonds and in addition to
participating as a member of various selling groups or as an agent of other
investment companies, executes orders on behalf of investment companies for
the purchase and sale of securities of such companies and sells securities to
such companies in its capacity as a broker or dealer in securities.

The Indenture provides that the Sponsor will not be liable to the Trustee,
any of the Trusts or to the Unitholders for taking any action or for
refraining from taking any action made in good faith or for errors in
judgment, but will be liable only for its own wilful misfeasance, bad faith,
gross negligence or wilful disregard of its duties. The Sponsor will not be
liable or responsible in any way for depreciation or loss incurred by reason
of the sale of any Securities in the Trust.

The Indenture is binding upon any successor to the business of the
Sponsor. The Sponsor may transfer all or substantially all of its assets to a
corporation or partnership which carries on the business of the Sponsor and
duly assumes all the obligations of the Sponsor under the Indenture. In such
event the Sponsor shall be relieved of all further liability under the
Indenture.

If the Sponsor fails to undertake any of its duties under the Indenture,
becomes incapable of acting, becomes bankrupt, or has its affairs taken over
by public authorities, the Trustee may either appoint a successor Sponsor or
Sponsors to serve at rates of compensation determined as provided in the
Indenture or terminate the Indenture and liquidate the Trust.

TRUSTEE

company with its office at Hancock Towers, 200 Clarendon Street, Boston,

any way for depreciation or loss incurred by reason of the sale by the
Trustee of any Securities in the Trust. In the event of the failure of the
Sponsor to act, the Trustee may act and will not be liable for any action
taken by it in good faith. The Trustee will not be personally liable for any
taxes or other governmental charges imposed upon or in respect of the
Securities or upon the interest on the Securities or upon it as Trustee or
upon or in respect of the Trust which the Trustee may be required to pay
under any present or future law of the United States of America or of any

THE UNITHOLDERS, SPONSOR AND TRUSTEE
THE PAINEWEBBER PATHFINDERS TRUST,
TREASURY AND GROWTH STOCK SERIES 22

We have audited the accompanying Statement of Financial Condition of The
PaineWebber Pathfinders Trust, Treasury and Growth Stock Series 22, including
the Schedule of Investments, as of January 29, 1998. This Statement of
Financial Condition is the responsibility of the Trustee. Our responsibility
is to express an opinion on this Statement of Financial Condition based on
our audit.

We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the Statement of Financial
Condition is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the Statement
of Financial Condition. Our procedures included confirmation with Investors
Bank & Trust Company, the Trustee, of an irrevocable letter of credit
deposited for the purchase of securities, as shown in the Statement of
Financial Condition as of January 29, 1998. An audit also includes assessing
the accounting principles used and significant estimates made by the Trustee,
as well as evaluating the overall Statement of Financial Condition
presentation. We believe that our audit provides a reasonable basis for our
opinion.

In our opinion, the Statement of Financial Condition referred to above
presents fairly, in all material respects, the financial position of The
PaineWebber Pathfinders Trust, Treasury and Growth Stock Series 22 at January
29, 1998, in conformity with generally accepted accounting principles.

Re: PaineWebber Pathfinders Trust,

Ladies and Gentlemen:

We have served as counsel for PaineWebber Incorporated as sponsor and

Stock, Series 22 (hereinafter referred to as the "Trust") in connection with
the issuance by the Trust of an initial 1,000,000 units of fractional undivided
interest in the Trust (hereinafter referred to as the "Units").

In this regard, we have examined executed originals or copies of the
following:

(a) The Restated Certificate of Incorporation, as amended, and
the By-Laws of the Sponsor, as amended, certified by the Secretary of
the Sponsor on the date hereof;

(b) Resolutions of the Board of Directors of the Sponsor adopted
on December 3, 1971 relating to the Trust and the sale of the Units,
certified by the Secretary of the Sponsor on the date hereof;

(c) Resolutions of the Executive Committee of the Sponsor adopted
on September 24, 1984, certified by the Secretary of the Sponsor on
the date hereof;

<PAGE>

(d) Powers of Attorney as set forth in the certificate of the
Secretary of the Sponsor dated the date hereof;

(e) The Registration Statement on Form S-6 (File No. 333-33037)
filed with the Securities and Exchange Commission (the "Commission")
in accordance with the Securities Act of 1933, as amended, and the
rules and regulations of the Commission promulgated thereunder
(collectively, the "1933 Act") and amendments thereto including
Amendment No. 1 ("Amendment No. 1") proposed to be filed on January
29, 1998 (the "Registration Statement");

(f) The Notification of Registration of the Trust filed with the
Commission under the Investment Company Act of 1940, as amended
(collectively, the "1940 Act") on Form N-8A, as amended, (the "1940
Act Notification");

(g) The registration of the Trust filed with the Commission under
the 1940 Act on Form N-8B-2 (File No. 811-4158), as amended (the "1940
Act Registration);

(h) The prospectus included in Amendment No. 1 (the
"Prospectus");

(i) The Standard Terms and Conditions of the Trust dated as of
July 1, 1997, between the Sponsor and Investors Bank & Trust Company
(the "Trustee") (the "Standard Terms");

(j) The Trust Indenture dated as of January 29, 1998 between the
Sponsor and the Trustee (the "Trust Indenture" and, collectively with
the Standard Terms, the "Indenture and Agreement");

(k) The Closing Memorandum dated January 29, 1998, between the
Sponsor and the Trustee (the "Closing Memorandum");

(l) Officers Certificates required by the Closing Memorandum;

(m) The form of certificate of ownership for units (the
"Certificate") to be issued under the Indenture and Agreement; and

(n) Such other pertinent records and documents as we have deemed
necessary.

With your permission, in such examination, we have assumed the
following: (a) the authenticity of original documents and the genuineness of
all signatures; (b) the conformity to the originals of all documents submitted
to us as copies; (c) the truth, accuracy, and completeness of the information,
representations, and warranties contained in the records, documents,
instruments and certificates we have reviewed; (d) except as specifically
covered in the opinions set forth below, the due authorization, execution, and
delivery on behalf of the respective parties thereto of documents referred to
herein and the legal, valid, and binding effect thereof on such parties; and
(e) the absence of any evidence extrinsic to the provisions of the written
agreement(s) between the parties that the parties intended a meaning contrary
to that expressed by those provisions. However, we have not examined the
securities deposited pursuant to the Indenture and Agreement (the "Securities")
nor the contracts for the Securities.

<PAGE>

We express no opinion as to matters of law in jurisdictions other than
the laws of the State of New York (except for "Blue Sky" laws) and the federal
laws of the United States, except to the extent necessary to render the opinion
as to the Sponsor and the Indenture and Agreement in paragraphs (i) and (iii)
below with respect to Delaware law. As you know we are not licensed to practice
law in the State of Delaware, and our opinion in paragraph (i) and (iii) as to
Delaware law is based solely on review of the official statutes of the State of
Delaware.

Based upon such examination, and having regard for legal
considerations which we deem relevant, we are of the opinion that:

(i) The Sponsor is a corporation duly organized, validly existing, and
in good standing under the laws of the State of Delaware with full corporate
power to conduct its business as described in the Prospectus;

(ii) The Sponsor is duly qualified as a foreign corporation and is in
good standing as such within the State of New York;

(iii) The Indenture and Agreement has been duly authorized, executed
and delivered by the Sponsor and, assuming the due authorization, execution and
delivery by the Trustee, is a valid and binding agreement of the Sponsor,
enforceable against the Sponsor in accordance with its terms;

(iv) The Trust has been duly formed and is validly existing as an
investment trust under the laws of the State of New York and has been duly
registered under the Investment Company Act of 1940;

(v) The terms and provisions of the Units conform in all material
respects to the description thereof contained in the Prospectus;

(vi) The consummation of the transactions contemplated under the
Indenture and Agreement and the fulfillment of the terms thereof will not be in
violation of the Sponsor's Restated Certificate of Incorporation, as amended,
or By-Laws, as amended, and will not conflict with any applicable laws or
regulations applicable to the Sponsor in effect on the date hereof;

(vii) The Certificates to be issued by the Trust, when duly executed
by the Sponsor and the Trustee in accordance with the Indenture and Agreement,
upon delivery against payment therefor as described in the Registration
Statement and Prospectus will constitute fractional undivided interests in the
Trust enforceable against the Trust in accordance with their terms, will be
entitled to the benefits of the Indenture and Agreement and will be fully paid
and non-assessable; and

(viii) While the Registration Statement has not yet become effective
we have no reason to believe that such Registration Statement will not become
effective on the date and at the time requested therein pursuant to Rule 487
promulgated under the 1933 Act.

<PAGE>
In addition, we have participated in conferences with representatives
of the Sponsor, the Trustee, the Trust's accountants and others concerning the
Registration Statement and the Prospectus and have considered the matters
required to be stated therein and the statements contained therein, although we
have not independently verified the accuracy, completeness or fairness of such
statements. Based upon and subject to the foregoing, nothing has come to our
attention to cause us to believe that the Registration Statement, as of the
date hereof, contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or that the Prospectus, as of the date hereof, contained an
untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading (it being understood that we have not been requested to and do not
make any comment in this paragraph with respect to the financial statements,
schedules and other financial and statistical information contained in the
Registration Statement or the Prospectus).

Our opinion that any document is valid, binding, or enforceable in
accordance with its terms is qualified as to:

(a) limitations imposed by bankruptcy, insolvency, reorganization,
arrangement, fraudulent conveyance, moratorium, or other laws relating to or
affecting the enforcement of creditors' rights generally;

(b) rights to indemnification and contribution which may be limited by
applicable law or equitable principles; and

(c) general principles of equity, regardless of whether such
enforceability is considered in a proceeding in equity or at law.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name wherever it appears in the
Registration Statement and the Prospectus.

Very truly yours,

CARTER, LEDYARD & MILBURN

Exhibit 8

January 29, 1998

Investors Bank & Trust Company

Boston, Massachusetts 02111

Dear Sirs:

As counsel for PaineWebber Incorporated (the "Depositor"), we have
examined an executed copy of the Trust Indenture and Agreement dated as of
January 29, 1998 (the "Indenture") and Standard Terms and Conditions of Trust,
dated as of July 1, 1997 (the "Agreement"), both between the Depositor and
Investors Bank & Trust Company, as Trustee. The Indenture established a trust
called PaineWebber Pathfinders Trust, Treasury and Growth Stock Series 22 (the
"Trust") into which the Depositor deposited certain United States Treasury
obligations, or evidences thereof, and stocks (the "Securities"), and moneys to
be held by the Trustee upon the terms and conditions set forth in the Indenture
and Agreement. Under the Indenture, certificates of ownership were issued on
the Initial Date of Deposit representing 1,000,000 units of fractional
undivided interest in the Trust (the "Units").

Based upon the foregoing and upon an examination of such other
documents and an investigation of such matters of law as we have deemed
necessary, we are of the opinion that, under existing statutes and decisions:

1. The Trust is not an association taxable as a corporation for
Federal income tax purposes. Under the Internal Revenue Code of 1986, as
amended (the "Code"), each Unitholder will be treated as the owner of a pro
rata portion of the Trust, and income of the Trust will be treated as income of
the Unitholder.

<PAGE>

2. Each Unitholder will have a taxable event when the Trust disposes
of a Security (whether by sale, exchange, redemption, or payment at maturity)
or when the Unitholder redeems or sells its Unit or redeems its units for cash.
For purposes of determining gain or loss, the total tax cost of each Unit to a
Unitholder is allocated among each of the Securities, in accordance with the
proportion of the Trust comprised by each Security, to determine the
Unitholder's per Unit tax cost for each Security.

3. The Trust is not an association taxable as a corporation for New
York State income tax purposes. Under New York State Law, each Unitholder will
be treated as the owner of a pro rata portion of the Trust, and the income of
the Trust will be treated as income of the Unitholders.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 333-33037) relating to the Units referred to
above and to the use of our name and to the reference to our firm in said
Registration Statement and in the related Prospectus.

Very truly yours,

CARTER, LEDYARD & MILBURN
